For parents

A short letter to parents.

A note to the parents who'll find this app on their kid's phone. What it does, what it doesn't, and how to think about it.

A mother shares a basket of fresh muffins with her daughter at a warm-lit kitchen table.

Hi. If you've come here because your daughter or your kid has TeenCycle on their phone and you want to understand it, this is for you.

The short version: TeenCycle tracks periods, lives entirely on the phone, and asks for no information about your kid. There's no account, no email, no profile, no friend list, no chat, no social anything. We don't have a parent dashboard, and there's no way to remotely view what's logged. Whoever has the phone can open the app and see what's there — the same as a note in their Notes app.

What this means in practice.

  • You can't get a copy of their data without picking up their phone.
  • We can't get a copy of their data, full stop.
  • There's nothing in the app that talks to other users, sells anything, or links out to the rest of the internet.

A small ask.

If your teen is in the room when you're reading this — let them keep this one private. Cycle data is medical information, and it's theirs. The act of tracking it independently is a small piece of growing-up that doesn't have to be supervised. Be available if they have questions. Otherwise, treat it the way you'd treat a private diary.

Cycle data is medical information, and it's theirs.

If you want to dig deeper, our offline-first piece explains why nothing leaves the phone. Our privacy policy is in plain English.

Thank you for taking the time. — L & M
